Sig Sauer Electro-Optics Sorx1530 Romeo-X Sig-Loc Pro Black Cerakote 1X 3 Moa Red Dot Reticle$579.99
Availability: In Stock
The Sig Sauer Romeo-X with SIG-LOC Pro mounting is a 1x pistol red dot built for shooters who demand rock-solid zero retention and a crisp sight picture under recoil. Unlike traditional top-mounted pistol optics, the Romeo-X uses an innovative bottom-mount design with five contact points between the optic and slide—a system refined through professional and military use—to eliminate the shift in zero that can come from shot-to-shot impact. The result is a sight that stays put, shot after shot.
The longer focal length inherent to the SIG-LOC design dramatically reduces parallax and reticle distortion, giving you a forgiving, distortion-free view whether you're running drill strings at the range or trusting it in a defensive role. At just 0.96 inches tall, it maintains co-witness height with standard iron sights, so you're not forced into a new sight picture. The 6 MOA red dot reticle strikes a balance—large enough for quick target acquisition in dynamic shooting, precise enough for accurate follow-ups at distance.
Built tough in 7075 aluminum with a fully sealed, enclosed optical system and IPX-8 waterproofing, the Romeo-X handles the punishment of duty or competition. The aspherical glass lens is distortion-free, and MOTAC (Motion Activated Illumination) keeps battery drain minimal—you're looking at 20,000 hours of run time on a single CR2032, with 15 illumination settings including three dedicated night vision modes. Side-loading battery access means you stay in the fight without removing the optic from your slide.
SIG-LOC PRO is the newest iteration of Sig's mounting standard, and it's fully backed by their Infinite Guarantee. The sight is assembled in the USA.

Yes. At 0.96 inches in height, the Romeo-X maintains standard iron sight co-witness height, allowing you to run irons alongside the dot.
The Romeo-X includes 15 illumination settings, with three dedicated night vision modes. You can pair it with night vision equipment when needed.
The optic uses a single CR2032 battery, loaded from the side without removing the sight from your slide. Battery life is rated at 20,000 hours with MOTAC (Motion Activated Illumination) enabled, which powers down the dot when motion is not detected.
